1 Claim.

My invention relates to improvements in fountain pens, and more particularly, has reference to and is illustrated in the accompanying drawing in its application to a pen in which dehydrated ink is carried so that by applying water the ink is formed and feeds to the pen much the same as in the more conventional form of fountain pen in which the ink is applied as such.

Referring to the accompanying drawing, I have illustrated in Fig. 1, partly in longitudinal section, a form of pen embodying an application of my invention, Fig. 2 is a cross-section thereof on the line 2-2 of Fig. 1, Fig. 3 is a plan view of one of the heads dividing the inner chamber, Fig. 4 a plan view of one form of partition, Fig. 5 a similar view showing a modification, Fig. 6 a cross-sectional view of a pen with a modified arrangement of partition, Fig. '7 a plan View of another form of partition, and Fig. 8 a suitable form of frame as applied in Fig. 6.

9 indicates the body of the pen and 10 an end section which may be screwed off from the threads indicated at II to expose the rubber bulb 12. In the center of the pen the two heads l3, M are provided, having cut-away portions 15, and may be provided with a slot 16 for turning the same by a screw-driver or other suitable means. Between these heads may be secured the partition I! such as shown in Fig. 4 or the form shown at 18 in Fig. 7. In the form shown in Fig. 4 the partition is recessed at opposite ends as indicated at I 9, l9, and in the form shown in Fig. 7 is kerfed as indicated at 20, 20', so that in either case the dehydrated ink 2| at one side of the partition is taken up in solution by water 22 at the other side of the partition.

In order to charge the pen after the dehydrated ink has been interposed therein, the usual form of screw cap 22 is first removed and the pen may be dipped into Water after the bulb 12 has been pinched between the fingers. By releasing the bulb now the water is drawn up through the pen and through the openings l5, remaining in the chamber 22, where by coming in contact with the dehydrated ink through the openings l9, 19 or 20, as the case may be, the ink thus formed feeds directly to the pen point in the usual manner.

In the modification shown in Figs. 6 and 8 a pair of rubber frames 23, 23 may be provided with an intervening coarse porous plate 24, so that the dehydrated ink at one side of the plate passes through into the water when moistened, and thus provides the necessary writing fluid instead of passing through openings such as 19 or 20. Also, as another modification a partition 25 may be employed similar in design to the partition l1, and a suitable wicklike or felt filler 26, 26' may be secured in the ends of the same to allow the ink to filter through the same slowly as required in writing, the object being to form the ink slowly from its dehydrated form as required, and so that when the water is exhausted and no ink is available, by simply drawing up additional water, new ink is formed thereby, and of course a suitable pocket clip such as 2'! may be employed in the usual manner.

In fact, new modifications may be made in the construction and arrangement of parts Without departing from the spirit of the invention as claimed.

I claim:

In a pen of the character described, a partition in the barrel thereof cut away at both ends, a screw threaded disc in said barrel againstthe lower ends of said partition and a hole through said disc, fillers in the cut away portions of said partition, ink producing sticks in the chamber formed between said partition and the barrel of said pen, and water at the opposite side of said partition.

CASIM'IR FIORE.
